Pseudo-Random Bit Generation based on 2D chaotic maps of logistic type and its Applications in Chaotic Cryptography

C. Pellicer-Lostao, R. Lopez-Ruiz

摘要:

伪随机比特生成(PRBG)在密码学的许多方面以及现代安全工程的其他应用中都是必需的。在这项工作中,PRBG的基础上的2D对称混沌映射的Logistic型。用这种类型的混沌PRBG产生的序列,统计测试和计算效率的发电机估计。考虑到该PRBG对密码学有效,还计算了可用密钥空间的大小。不同的密码应用程序可以适用于这个PRBG,作为流密码可能是其中最直接的。

英文摘要:

Pseudo-Random Bit Generation (PRBG) is required in many aspects of cryptography as well as in other applications of modern security engineering. In this work, PRBG based on 2D symmetrical chaotic mappings of logistic type is considered. The sequences generated with a chaotic PRBG of this type, are statistically tested and the computational effectiveness of the generators is estimated. Considering this PRBG valid for cryptography, the size of the available key space is also calculated. Different cryptographic applications can be suitable to this PRBG, being a stream cipher probably the most immediate of them.
